Title:
LAYERED INDUCTOR
Document Type and Number:
WIPO Patent Application WO/2014/155952
Kind Code:
A1
Abstract:
The present invention provides a layered inductor capable of reducing differences in inductance values and suppressing the occurrence of magnetic interference by using a simple method. According to the present invention, a plurality of electrically insulating magnetic layers (2) and conductive patterns (3a) are layered, each of the conductive patterns (3a) being connected in sequence in the layering direction, whereby two coils (3) are formed having substantially the same number of turns and the same coil diameter, the two coils (3) having a mirror-image relationship in relation to a hypothetical plane between the coils (3), the mutual end sections (4) being disposed in parallel and positioned in the outer peripheral section on the opposite side from the hypothetical plane, electrically insulating nonmagnetic patterns (5) having the same shape being disposed between the conductive patterns (3a) adjacent in the layering direction, and at least one electrically insulating nonmagnetic layer (6) being arranged, only inside the coils (3), in the layering direction in place of the magnetic layers (2).
